ANTIREFILLABLE BOTTLE.

Specification of Letters Patent.

Patented May 4, 1915.

f Application filed June 19, 1914. Serial No. 846,125.

To all whom it may concern:

. Be it know that I, HENRY F. SoHUL'rz, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Antire- ,fillable Bottles, specification.

The object of the present invention is to provide an anti-refillable bottle, or more strictly speaking, an anti-refillable stopper for bottles designed for dispensing liquid therefrom only in limited I quantities and whichwill effectively prevent or render difficult the refilling of a bottle once emptied of its original contents.

More particularly, the essence of the invention lies in the provision of a stopper comprising a valve member which normally closes the passage into the bottle when in its usual upright position and also when in its inverted position, but being of a movable character permits the passage of a small quantity of the liquid from the bottle during its movement of unseating and seating. To this end the valve employed is formed with spaced heads connected by a valve stem operating through the valve seat, said valve being operable upon inversion of the bottle to unseat one head and seat its other, admitting, however, as hereinbefore mentioned, the liquid to pass through the valve seat during the moving intervals of the valve member or when said bottle is shaken or agi tated in its inverted position.

These and such other objects as may hereinafter appear are attained by the novel construction, combination and arrangement of parts to be hereinafter specifically described and claimed.

Reference will now be had to the accompanying drawings forming apart of this specification, wherein Figure 1 is a side elevation of a bottle forming the embodiment of my invention. Fig. 2 is a fragmentary vertical sectional view showing the bottle in inverted position and the valve member ready to check the flow of the liquid from said bottle. Figs. 3, 4 and 5 are top plan, vertical sectional, and bottom plan views, respectively, of the valve casing. Fig. 6 is a side elevation of a spring locking member for the valve casing. Fig. 7 is a bottom plan view of the same, showing the locking flanges. Fig. 8 is a transverse sect onal vie on the line 8-8 of Fig. 2.

of which the following is a Fig. 9 is a view partly broken away and partly in section of a permanent cap member for the bottle. Fig. 10 is a detail view of the valve member alone.

Referring to the drawings, the bottle 1 is formed with the usual neck 2 which is pro vided interiorly at one end with an annular shoulder 3. In the neck 2 is disposed the valve casing 4 of cylindrical shape and hav- 8 preferably being employed around the upper end adjacent the annular flange 5 to hold it properly in its spaced relation.

The lower portion of the casing is surrounded by a locking member 9 which is connected to the casing in any desired manner and formed with diametrically opposite spring legs 10, each of which is provided with a locking flange 10 interlocking beneath the shoulder 3 of the neck. A valve seat 11 is formed near the lower end of the casing 4 and said seat is provided with a spider 12 through which the stem 13 of the valve member extends, said spider guiding the valve member in its movements for seating its heads at opposite sides of the valve seat. The stem is provided at each end with a head or ball 14, one of which seats on the valve seat at one side when the bottle is in normal upright position to prevent filling of the bottle and the other being adapted when the bottle is inverted to seat on the other or under side, the stem being of sufiicient length to permit passage of the fluid through the seat while the valve stem is moving freely up and down under agitation or when the bottle is being inverted. The liquid passes through an opening 15 in the gasket 7, out through the nozzle 16 of the crimped cap 6. A screw cap 17 is provided for the nozzle when so desired.

It will be appreciated from the foregoing descriptionthat the bottle construction contemplated by this invention is adapted particularly for use in conjunction with liquids such as. cologne where only a limited or small quantity of the liquid is desired to be utilized and yet of a sufficiently protective character to prevent or render extremely diflicult the refilling of the original container. The assembling of my stopper may be summarized as follows. The valvemember is disposed with its stem through the valve seat by the removal of a ball at one of its ends and the packing 8 disposed about the upper portion of the casing 4. The locking member 9 is then positioned upon the lower portion of the casing and secured in any desired manner thereto. The casing is then inserted into the neck of the bottle and by reason of the spacing between the casing and the interior wall of the neck the flanges 10 or the legs 10 will be permitted to pass through the entrance and to expand, said legs expanding as soon as said flanges reach the annular shoulder 3 interlocking thereby the valve casing against movement outwardly of the bottle. The cap 6 is then crimped in position on the entrance by any of the well known methods, pressing against the fiange zi and locking the valve casing against inward movement with respect to the bottle.

Gbviou'sly the device is extremely simple and capable of being cheaply manufactured for performing the limited service of devices of this character.

E-laving thus described the invention, what is claimed as new is Copies of thispatent may he obtained for A bottle stopper of the class described comprising in combination with a bottle neck, a valve casing of cylindrical form having an annular flange at its upper end for seating against the entrance of the neck, said casing being of a smaller diameter than. the cross sectional area of the entrance to the bottle, a locking member of a larger diameter than the valve casing and disposed thereupon at its lower end, said locking member having depending spring legs formed with engaging flanges adapted to interlock with the bottle neckupon insertion of the casing thereinto, a seat formed in the neck and having an opening therethrough, a valve member operable in said casing and comprising a stem having heads at opposite ends thereof adapted to seat at opposite sides of said valve seat to close the passage through the neck, a packing member surrounding a portion of the casing and holding the same spaced from the interior wall of the neck at one end, a cap member crimped upon the neck, and a second packing member intermediate the cap and the entrance-to the neck clamped against the flanged extremity of the casing to hold said casing from movement into the bottle.

In testimony whereof I ailix my signature 1 in presence of two witnesses. I I
